SKL Elastic rail clip function
Like other rail fasteners, the main function of rail clip is fastening railway sleeper and steel rail together. The rail clip is considered as one of the best ways to ensure that rails do not move, bend, warp, or rot. There are data shows that each elastic rail clip can bear about two tons of force upon a railway track.
